Seem to be a staple boot for many companies as a rental boot. Good reason too they are generally comfortable for a wide assortment of people. The double plastic boot is warm if you are going to be in extreme cold a insulated over-boot may be a worthwhile addition to these. The boots perform well whether you are doing technical ice or a mountain route involving a lot of walking. They can accept any style of crampon.
The insulation on these boots is good but not fantastic. If you are going to be doing technical ice all the time these are not the boots you want. But if you want a boot that can do it all pretty well it's something to look into.
Want a double boot thats a little bit more technical Look into the Scarpa Omega.
Warm, Durable, flexible and walkable. There is a lot of talk about the nimbleness of new boots, but after climbing with a couple of Britain's top alpinists I found the great benefits often out weigh the draw backs.
Removable liners can dry over night
Plastic is waterproof
Plastic does break in to become more nimble but it takes a while. Had mine 3 years now.
Hard to find in the US now, greater learning curve to handle than leather boots.
